“…K ale is considered an annual or biennial cycle crop and the leaves are harvested periodically throughout its vegetative cycle. The leaves have high nutritional content, being rich in carotenoids, vitamins C and K, phenolic compounds and organic acids (Sikora et al, 2008;Null & Feldman, 2011), antioxidant and antimicrobial properties, and some herbal properties, acting on gastric ulcers and many types of cancer (Vilar et al, 2008;Agbaje & Okpara, 2013).…”

An adequate use of brackish water in agricultural production is one of the main challenges for researchers and rural producers, since saline stress may cause physiological and nutritional changes in plants, affecting the crop yield. An appropriate mineral nutrition is essential for plants, grown under saline stress, to express their productive potential. The aim of this study was to evaluate the mineral nutrition and hydroponic kale production under saline stress and calcium nitrate. The experiment was carried out using one hydroponic system in substrate, following a randomized block design, with five treatments and four replicates. The treatments consisted of five nutrient solutions, with a control treatment {S1 = standard nutrient solution using low salinity water, 0.5 dS/m [750 mg/L of Ca(NO3)2]}, and four nutrient solutions prepared using brackish water (6.0 dS/m) containing four concentrations of Ca(NO3)2 (S2 = 750 mg/L, S3 = 1,125 mg/L, S4 = 1,500 mg/L, S5 = 1,875 mg/L). We determined the levels of N, P, K, Ca, Mg and S in leaf tissue at three evaluation times (50, 64 and 78 DAT). Mineral levels in the leaves, stem and root were also evaluated at the end of the experiment (100 DAT). In addition, leaf production and the agronomic efficiency of Ca(NO3)2 were verified. The highest leaf production (1780 g/plant) and agronomic efficiency [2.37 g fresh matter/mg of Ca(NO3)2] were obtained in the standard nutrient solution, and both were reduced at 55.6% by salinity. The extra addition of 50% Ca(NO3)2 in the saline nutrient solution reduced the effect of salinity on Mg absorption and the effect of NaCl addition on kale production.

Diets containing high proportions of fruits and vegetables reduce the risk of onset of chronic diseases. The role of herbal medicines in improving human health is gaining popularity over the years, which also increases the need for safety and efficiency of these products. Green leafy vegetables (GLVs) are the richest source of phenolic compounds with excellent antioxidant properties. Increased consumption of diets containing phenolic compounds may give positive and better results to human health and significantly improves the immune system. Highly selective, susceptible and versatile analytical techniques are necessary for extraction, identification, and quantification of phenolic compounds from plant extracts, which helps to utilize their important biological properties. Recent advances in the pre-treatment procedures, separation techniques and spectrometry methods are used for qualitative and quantitative analysis of phenolic compounds. The online coupling of liquid chromatography with mass spectrometry (LC–MS) has become a useful tool in the metabolic profiling of plant samples. In this review, the separation and identification of phenolic acids and flavonoids from GLVs by LC–MS have been discussed along with the general extraction procedures and other sources of mass spectrometer used. The review is devoted to the understanding of the structural configuration, nature and accumulation pattern of phenolic acids and flavonoids in plants and to highlighting the recent developments in the chemical investigation of these compounds by chromatographic and spectroscopic techniques. It concludes with the advantages of the combination of these two methods and prospects.

Determination of the optimal number of evaluations in half-sib progenies of kale by Bayesian approach

et al. 2021

Kale has a long vegetative cycle, requiring a lot of labor, due to the need for tutoring, thinning and multiple harvests, leading to difficulties in the maintenance and evaluation of experiments. Thus, the objective was to estimate the minimum number of evaluations for the assertive selection of half-sib progenies of kale by means of a repeatability study by Bayesian approach. Twenty four half-sib progenies were evaluated in a randomized block design with four replicates and five plants per plot. The number of shoots, number of marketable leaves, fresh mass of marketable leaves and fresh mass per leaf were measured throughout 15 harvests. All traits showed high estimates of the repeatability, indicating high regularity in the expression of the traits during the harvesting period. With eight harvests it is possible to evaluate all the traits with a coefficient of determination superior to 85% in half-sib progenies of kale.
